    base-files: uci-defaults: allow setting wireless defaults
    
    Introduce new uci-default functions:
     - ucidef_set_wireless band ssid [encryption] [key]
     - ucidef_set_country cc
    
    They are supposed to be used in /etc/board.d/* scripts to define
    board-specific defaults for wireless.
